PROJECT 4
Implement design interface and display of animated wallpaper patterns of
animated gifs
This project is divided into 3 parts, each involving your code and video
presentations to display:
A - all wallpaper groups with provided static figure “F”
B - your cool animated gif to replace the figure “F”
C - an animated COTS warp of the whole pattern (may use all or part of Jarek’s code provided)
COTS animation and annulus
Base Code
Base code can be found on Canvas under Files.
Wallpaper patterns: Files/P4 patterns/wallpaperBaseCode.zip
COTS: Files/P4 patterns/COTS sketch.zip
Base Code
Implement the functions in
Student tab.
Each function has comments that
may help with the
implementation.
Running the base code
Symmetries for wallpaper group 2
(TUTVR2) have already been implemented
for you.
Translation vectors U and V shown in
green.
Output shows pattern of the letter “F”
having these symmetries.
Part 1: Wallpaper groups
Implement the following functions:
Mirror(P, MC, MV): Returns reflection of P through axis (MC,MV)
Glide(P, MC, MV, d): Returns glide reflection of P about axis (MC, MV) with
translation amount d.
Part 1: Wallpaper groups
Implement the following functions:
setWallpaperSymmetries(): sets the generating symmetries for each of
the 17 wallpaper patterns.
Implement for the remaining 16 wallpaper groups (case 0 and cases 2-
16).
Provided
for reference
Implement
remaining cases
Expected output of Part 1
Expected output images for each of the 17 wallpaper patterns can be found
in the folder wallpaper/PICTURES
Part 2: Design animated shapes
Base code provides a function that draws
simple geometry (“F” shape).
Modify or use this as reference to create
your own beautiful shapes.
Some possible ideas:
● Flowers
● Circle packing
● Kaleidoscope patterns using image
textures
Part 3: COTS Mapping
Apply the COTS mapping to the
wallpaper pattern created in Parts 1 and
2.
GUI provided
‘f’: Toggles display of the letter “F”.
‘0’: Switches between wallpaper patterns.
‘>’: Toggles display of the origin and translation vectors
‘G’: Toggles display of the fundamental region
‘g’ : Toggles display of the grid
Mouse drag + ‘m’/’r’/’s’: Translates/rotates/scales the geometry of shape “F”.
Mouse drag + ‘u’ or ‘v’: Modifies the U and V vectors respectively.
Deliverables
This is an individual project.
Project is due April 19 before class.
Submission via a zip file containing the following:
Working code
Report (pdf)
● Description of problem statement
● Brief details on how you implemented each section of the project.
Video of an aesthetic animation!
Extra credit options
Create circle packings inside wallpaper patterns.
Create periodic tilings (allowing edges between instances of the same vertex)
Alternate generating symmetries for the same wallpaper groups.
Design non-periodic and aperiodic patterns.
3D extensions: raised 3D pattern, warp using XMAP.
